During detection, the coupling oil flows out through the oil outlet pipes on the two sides of the probe 17 to fill the gap between the probe rod 205 and the hollow shaft, so that the direct contact between the detector and the hollow shaft is avoided, and the purpose of reducing abrasion and protecting the detector is achieved.
An oil temperature controller is arranged in the oil tank 204, is installed at the bottom of the oil tank 204 and is used for controlling the oil temperature. The power line of the oil temperature controller is led out through a 2-core aviation plug at the top of the oil tank 204 and connected to an external 24V power interface of the ultrasonic electronic controller 206, and the design can effectively reduce the loss of coupling oil and improve the accuracy of oil temperature control;

One network card of the image processor 402 is connected with the network communication interface of the pan-tilt camera 401 through a network cable, and the other network card is connected with the network communication interface of the central controller 403 through a network cable. Therefore, the image processor 402 can send a collecting instruction to the pan-tilt camera 401 to control the pan-tilt camera 401 to collect the vehicle number image information. Meanwhile, the image processor 402 may receive the car number image information captured by the pan/tilt camera 401, automatically locate the car number region in the car number image information and identify the car number information in the region, including information such as the position of the vehicle, the position of the axle, and the like, by using a machine learning algorithm.

The image information of the car number shot by the station camera 401 is transmitted to the image processor 402 through the network, the image processor 402 identifies the car number information in the image information of the car number through a machine learning algorithm, and then transmits the obtained car number information to the central controller 403 through the network.
Since the vehicle position and the axle position in the vehicle number information are relatively fixed in the geometry of a train of motor cars, the position relation of the flaw detector relative to the whole train of motor cars can be deduced from the vehicle number information obtained by the central controller 403, so that the detection progress can be tracked.
After the detection is finished, the central controller 403 compares the actually detected axial position information with the planned detected axial position information, and if the actually detected axial position is missing, the missing axial position can be determined. Once the detection is found to be missed, the central controller 403 calls a specific voice file to send out a prompt tone to remind a flaw detector to make up the detection, so that the function of early warning of the detection is realized. Meanwhile, the central controller 403 can also automatically fill in a 'ultrasonic flaw detection record sheet for hollow axles of a motor train unit', fill corresponding contents in the axle position, axle type, axle number, entry end and accumulated travel mileage according to the historical information of the detected vehicles called from the database of the central controller, thereby realizing the automatic meter filling function.
